The machine for producing bags from a plastic film web (7) with welding devices (1, 2) which are intended for sealing the bag ends and circulate on both sides of the film web (7) and of which welding devices two opposite ones (1, 2) interact in each case, is characterised in that rolls (12, 13) circulate synchronously with the welding devices (1, 2) on both sides of the film web (7), of which rolls (12, 13) two opposite ones in each case interact, enclosing the film web (7) between them, one of the rolls (13) in each case of each interacting roll pair being drivable in a rotating manner over a part of the path. <IMAGE> |
